Doesn't really care

On the 27th of March I purchased 3XBig Mac meals at the drive through.<br> When I got home I realized I had only been given 2 meals.<br> I tried to call the branch but the phone was not picked up.<br> I logged a complaint on the McDonalds website.<br> I did receive a call and I confirmed the details of the incident.<br> One week later, I get another call and I am asked to produce the slip for the purchase.<br> I informed the person that the slip number had been part of the original complaint that I logged.<br> She told me that she wouldn't be able to help me without the slip.<br> I told her my opinion of the service I had received so far.<br> Next day, I receive and email telling me that my query has been resolved<br> I rep****, challenging that it had been resolved.<br> Next day I receive a call from the branch manager. I was busy and asked him to call me back after a few hours. That was 3 days ago and I haven't heard anything.
